Subject: [PATCH] Exiles Reach: rider immune to NPC damage while on the giant
 boar

Some undead still hit the player during the boar ride (mobs that aggro on
sight, not via the trample). Set UNIT_FLAG_IMMUNE_TO_NPC on the player for
the ride's duration so mob attacks can't reach the rider (IsValidAttackTarget
checks target->IsImmuneToNPC); the boar takes the hits and the trample kills
the cadavers.
